When Apple's iPhone 5 launches, it will do so in three models: CDMA, CDMA EV-DO Rev. A, and CDMA EV-DO Rev. B. As was previously expected, the new iPhone will also feature the nano-SIM design proposed by Apple and accepted as standard by international telecom standards bodies. The reason for the different models for the newest iPhone is thought to be related to the LTE infrastructures of some wireless carriers.
